YETI Rambler 12 oz Colster Can Insulator — Seafoam, Standard 2.0 with Double-Wall Vacuum & Load-and-Lock

The YETI Rambler 12 oz. Colster is a rugged seafoam-colored can insulator that locks onto standard 12 oz cans to keep drinks cold and hands dry without the extra can insert.

Built from thick-gauge steel with a double-wall vacuum, this Colster 2.0 pairs a simple quarter-turn Load-and-Lock gasket with YETI’s Duracoat finish so your beverage stays colder longer and the exterior resists chipping. Designed for standard 12 oz cans and many longnecks, it’s a low-maintenance accessory for outdoor gatherings, tailgates, and long, hot days.

Will this Colster keep my drink cold at a summer barbecue?

Yes — the double-wall vacuum insulation minimizes heat transfer so your can stays colder far longer than an uninsulated container. While it won’t make a warm drink cold, it preserves the chill of a refrigerated beverage in hot conditions.

• Double-wall vacuum insulation reduces warming from outside temperatures.
• Thick-gauge steel adds thermal mass for extended cold retention.
• Duracoat exterior resists wear from outdoor use and handling.
• Load-and-Lock gasket seals with a quarter-turn to reduce air exchange.

How does the Load-and-Lock gasket work and is it easy to use?

The Load-and-Lock gasket is a simple quarter-turn mechanism that secures a standard can in place and helps prevent warm air from reaching the beverage. It’s intuitive to operate and quick to engage, making swapping cans fast during parties or events.

• Place the can, twist a quarter-turn, and the gasket locks the can into the Colster.
• The sealed fit reduces condensation and keeps hands dry.
• Works with most standard 12 oz cans and many longneck bottles (fit varies by shape).

Is this version different from earlier Colsters and how should I clean it?

This model is the Standard Colster 2.0 and does not include the previously packaged Stash Can. It retains the same durable steel construction and Duracoat color. For maintenance, the Colster is dishwasher safe for convenient cleaning.

• Does not include the Stash Can—this is the insulator only.
• Duracoat finish minimizes cracking and chipping over time.
• Dishwasher safe for easy cleaning; rinse gasket and dry thoroughly between uses.

Who is this for: The YETI Rambler 12 oz. Colster in Seafoam is ideal for outdoor enthusiasts, tailgate hosts, and anyone who wants a durable, easy-to-use can insulator that preserves temperature and minimizes condensation. It’s best for people who use standard 12 oz cans or longnecks and want a low-fuss, long-lasting product that stands up to frequent outdoor use.
